摘　　要：基于光纤传输系统的手机信号屏蔽系统采用了干扰效率更高的新型数字扰码技术并结合光纤分布架构的组网方式,区别于目前采用室内分布系统架构的数字屏蔽系统,它不需要建设复杂的天线室内分布系统,降低了数字扰码屏蔽技术应用的施工门槛,提升了系统组网能力,同时还能对末端屏蔽节点进行远程控制,在实现低辐射、全制式、不干扰基站、周界控制精准的前提下还能降低系统造价,利于系统推广。The mobile phone signal shielding system based on optical fiber transmission system adopts a new digital scrambling technology with higher interference efficiency and combined with the networking mode of optical fiber distribution architecture.It is different from the current digital shielding system based on indoor distribution system architecture.It does not need to build a complex antenna indoor distribution system,which reduces the construction threshold for the application of digital scrambling shielding technology.It not only improves the networking capacity of the system,but also remotely controls the end shielding nodes.On the premise of low radiation,full system,no interference with the base station and accurate perimeter control,it can also reduce the system cost and facilitate the promotion of the system.
